A scientist wanted to know more about these blue birds at a beach. He goes to the beach and he writes down everything he sees the birds doing and all the sounds they make. This is an example of which scientific tool?

• Observational Investigation

• Comparative Investigation

• Experimental Investigation

• Hypothesis Investigation

Mark wanted to find out if salt water evaporates faster than pure, fresh water.  He formulated a hypothesis and then placed 100 mL of fresh water in a beaker.  He placed 100 mL of salt water in another beaker.  He placed both beakers on the same hot plate. Mark then watched the beakers and timed how long it took the water to evaporate.  He then analyzed or studied and recorded the results. Which type of scientific investigation did Mark use?
